To all whom it may concern:

Be it known that I, RICCARDO VoL'roLINI, a citizen ofthe Kingdom of Italy, residing at Waterbury, in the county of New Haven and State of Connecticut, have invented new and useful Improvements in Ventilated Shoes, of which the following is a specification.

This invention comprehends the provisionV of a ventilated shoe, having a narrow pocket at the heel of the shoe, to establish communication between the interior of the shoe and the atmosphere, this cushioning d evicearranged within the shoe and operating within the depression and the lift, to provide for the circulation of air within the shoe.

Another object of the invention resides in the provision 0f an insole for the shoe, which is perforated, and also provided with continuous strips on one side which are spaced defining continuous channels through which the fresh air is forced so as to ventilate the shoe over the entire area of the insole.

The nature and advantages'of the invention will be better understood when the following detail description is read in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawings forming part of this application like numerals of reference indicate similar parts in the several views, and wherein l Figure 1 is a rear elevation of the shoe constructed in accordance with the invention.

Fig. 2 is a transverse sectional view through the shoe looking in the directiony of the heel thereof.

Fig. 3 is a sectional view angles to Fig. 2.

Fig. 4 is a plan view of the heel lift. Fig. 5 is a plan view of the insole. Fig. 6 is a detail view of the cushioning member. l

In accordance with the presentinvention,

I provide the heel portion 10 of the shoe with spaced openings 11 which are covered at one side by a strip of suitable material indicated at 12, and secured to the inside of the heel portion of the shoe to define by the intervening space therebetween air-pockets 13. The strip is cut away at its lower edge at spaced intervals to provide a plurality of openings 14 which together with the` taken at right i specification of Letters retenu 'patented Feb 22,192L Application inea :rune 14, 1920.VV serial no. 388,957. y,

openings llmestablish communication between thel interior of the shoeand the atmosphere through vtheV air pocket 13. The heel portion proper including the lift 15 isl formed with a depression 16 in which is arranged a cushioning member such as is illustrated in Fig. 6. rlhe cushioning member embodies upper and lower plates 17 and 18 respectively, which are connected together by means of a coiled spring 19. The upper plate is provided with a 'plurality of spaced openings at 2O to admit the fresh air into the shoe from the pocket 13.

Forming a part of the shoe is an insole 21 which is perforated as at 22, one side of the sole being providedl with a plurality of spaced inlets 23, which define continuous channels 2li-to convey the fresh air to all parts of the .shoe over the entire area of the sole. 'Ihe outermost strip 23 iscut away at spaced points 'adjacent the heel portion of,`

the sole, to provide passages 26 communicating with the openings 12, so that the air admitted to the shoe from the pocket 13 may enter the channels defined by the spaced openings between this outermost strip and the next strip 23. The insole is provided with an opening 27 adjacent the heel which co-incides with one of the openings in the uppermost plate 17 of the cushioning member so as to admit air into the channel defined by the space between the other strips of the sole as shown in Fig. 5. AIn the prac? Vwater, snow or the like gaining access to the shoe through these openings.

While it is believed that from the foref going description, the nature and advan-v tages of the invention will be' readily apparent, I desire to have it understoodthat I do not limit myself'to what is shown and described, and that such change may be resortedl to when desired as fall within theV scope of'what is claimed.

What I claim is A shoe having a pair of spaced openings in the heel portion of the shoe upper, a piece soV of material arranged within the shoe and having one end overlying said openings, and

its opposite endtermnating immediately. above the heel lift of the shoe, said lower end of the material having a' plurality of openings to establish communication between the pocket defined by the intervening space between the heel portion of the shoe and said piece of material, and the interior of the` shoe, a perforated insole, strips extending about the under side of the insole to provide channels, the outermost strip bepiece of material, a cushioning device embedded in the heel lift beneath the insole and operating to create a circulation of air within the shoe, and said insole havingan opening immediatelyabove the cushioning de 20 .Y vice as described.

In testimony whereof. I aiiiX- my signature;

RICCARDO voLToLiNI'.
